GROVER C. BENTINCK AND HENRY W. BENTINCK, OF GALVESTON, TEXAS.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed May 8, 1912. Serial No. 695,981.

To all whom it may concern:

Be it known that we, GRovER C. BENTINCK and HENRY IV. BENTINCK, citizensof the United States, residing at Galveston, in the count-y of Galvestonand State of Texas, have invented new and useful Improvements inNon-Refillable Bottles, of which the following is a specification.

This invention relates to non-refillable bottles and the object of theinvention is to provide a simple and efficient device of this characterwhich may be cheaply constructed and which willeifectually prevent therefilling of the bottle after the original contents have been dispensed.

A further object of the invention is to provide a novel form of lockingmechanism to hold the stopper within the neck of the bottle withoutforming shoulders or channels in the bottle neck.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawings, whichform a part of this application, and in which Figure l is a sectionthrough a bottle neck showing the stopper mounted therein. Fig. 2 is alongitudinal sectional view through the stopper showing the alternativeposition of the ring in dotted lines. Fig. 8 is a horizontal sectiontaken on the line 33 of Fig. 2. Fig. 4 is a similar view on the line 44of Fig. 2.

Referring more particularly 'to the drawing, 1 represents a stopper bodypreferably of porcelain or other similar material which is provided witha central bore 2 in its upper end and with a plurality of channels 3 eX-tending through the body and communicating with the bore 2 at the upperend and with a similar bore or recess 4 at the lower end. These channelsare so arranged in the body with half of their diameter less than thebores 2 and 4 and the other half lies within the area of said bores.Secured in the lower bore 4 is a conical valve seat member 5 which isprovided with a central bore 6 and a valve seat '7 at its upper end uponwhich the valve 8 is adapted to rest. This valve is provided with a stem9 extending through the same and adapted to enter a central socket 10formed in the body of the stopper and extending upwardly from the bore4. The valve member 5 projects only a short distance in the body of thestopper so as to produce a valve chamber 11 in which the valve moves.Surround ing the valve seat member is a split metallic ring 12, whosediameter is substantially the same as the interior of the valve neck andwhich is loose upon the valve seat member when seated against thestopper body, as shown in dotted lines in Fig. 2. IVhen the stopper isforced into the neck, the ring will be raised into engagement with thestopper. After the stopper has been placed in the neck, the ring willdrop down on the large end of the conical valve seat member and anyattempt to remove the stopper from the bottle neck will result in saidvalve member expanding the ring in the bottle neck which thus locks thestopper against outward movement. In practice, this type of stopper ispreferably used in connection with bottles having their necks providedwith straight inner walls or the bottle neck may have a slight inwardbulge over which the ring will ride by slight contraction. Such a typeof neck has been illustrated in the drawings at 13 and the inward bulgeindicated at 14.

that is claimed is 1. In combination, a bottle neck having an interiorbulge, a stopper having a reduced and tapered lower end smaller than thediameter of the neck at said bulge, and a split ring mounted upon thetapered portion and adapted to engage the side of the bulge and lock thestopper against removal.

2. In combination, a bottle neck having an interior annular bulge, astopper body, a reduced valve member secured to the stopper body andhaving an outward taper, and a central passage, a split ring mountedupon said valve member and having a diameter less than the diameter ofthe bottle neck at the bulge, said ring adapted to seat against theunder side of the bulge and lock the stopper against removal from theneck, and a valve for closing the central passage through the stoppermember.

3. In a non-refillable bottle, the combination with a bottle neck, of astopper body mounted therein, said body having bores or socketsextending inwardly from opposite ends, longitudinal channels in thebody,
